Answer:
C. oxygen atom
Explanation:
H2O contains two hydrogen atoms and one oxygen atom.
Oxidation state of Pb in PbO2 is +4.
Oxidation state of Pb in PbCl2 is +2.
Oxidation state of Pb in Pb2O is +1.
Oxidation state of Pb in Pb4O3 is +6/4.
Hence option A. PbO2 is correct.
Hope this helps, have a nice day!
The answer is that exact locations within either cannot be determined at any given moment in time.
An electron cloud be compared with a spinning airplane propeller in the manner that in both exact location within either cannot be determined at any given moment in time.
In both electron cloud as well as spinning airplane propeller, there is a probability of finding either but exact location can not be determined.
- No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>
Now
- It has atomic no 15 hence its Phosphorus(P)
Electronic configuration:-
.
Chloride formula:-
or.
